Why does the gentlewoman in Act V, scene i refuse to repeat Lady Macbeth's sleep-talk to the
doctor?
The words are mumbled and impossible to understand,
Lady Macbeth forbade her to reveal the murders to anyone.
There is no witness to confirm the truth of the gentlewoman's words.
The gentlewoman thinks that only the doctor will believe her

When the doctor asks the gentlewoman to report what she has noticed, she refuses to do that for two reasons. Firstly, she probably refuses to tell the doctor about Lady Macbeth's strange behavior because she is her gentlewoman, so she should take care of her and be loyal to her.

the tone of the passage is sympathetic to the forbidden love of romeo and juliet. the nurse plays a significant role in the play. she is responsible for making their meeting again possible. additionally, there is a sense of warning in the choice of words of the nurse. she seems to be authoritative when she calls romeo "scurvy knave", and at the same time the fact that she addresses to him as "sir" reflects respect. the nurse is "vexed", this word describes her confused state of mind. on the one hand, she finds romeo a fine and eloquent man, but on the other, it is thought that man's nature forces men to try to trick women.
